### Extending Ingress with and replacing a deprecated annotation with IngressClass

In Kubernetes 1.18, there are two significant additions to Ingress: A new `pathType` field and a new `IngressClass` resource. The `pathType` field allows specifying how paths should be matched. In addition to the default `ImplementationSpecific` type, there are new `Exact` and `Prefix` path types. 

    public boolean isOnlineRequired() {
        return onlineRequired;
    }

    /**
     * @return <code>true</code> if the Mojo is online, <code>false</code> otherwise.
     */
    // more english-friendly method...keep the code clean! :)
    public boolean requiresOnline() {
        return onlineRequired;
    }

    /**
     * @return the bound phase name of the Mojo
     */
    public String getPhase() {

	if errCode != ErrUnsignedHeaders {
		t.Fatalf("Expected the APIErrorCode to %d, but got %d", ErrUnsignedHeaders, errCode)
	}

	// case where the list of signed headers doesn't contain the host field.
	signedHeaders = signedHeaders[2:5]
	// expected to fail with `ErrUnsignedHeaders`.
	_, errCode = extractSignedHeaders(signedHeaders, r)
	if errCode != ErrUnsignedHeaders {

After a week, the token will be expired and the user will not be authorized and will have to sign in again to get a new token. And if the user (or a third party) tried to modify the token to change the expiration, you would be able to discover it, because the signatures would not match.

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.
